DEVICE TO DRY CATALYST ROASTER CONVEYOR BELT AND METHOD OF USING SAME

摘要

A system (10) and process for removing an inorganic salt from a catalyst roaster belt (26) is disclosed. The system (10) includes an apparatus with a drying vessel (56) having a catalyst roaster belt inlet (51), a catalyst roaster belt outlet (30), a heating medium inlet (72), and a heating medium outlet (74), wherein the catalyst roaster belt inlet (51) and the catalyst roaster belt outlet (30) are spaced apart along a first direction, the heating medium inlet (72) and the heating medium outlet (74) are spaced apart along a second direction, the heating medium inlet (72) is spaced apart from the catalyst roaster belt inlet (51) in the second direction, and the catalyst roaster belt inlet (51) is between the heating medium inlet (72) and the heating medium outlet (74) along the second direction. The system (10) includes an acid bath (12) and a moveable catalyst roaster belt (26) extending from the acid bath (12) through the catalyst roaster belt inlet (51) and through the catalyst roaster belt outlet (30). The process includes the steps of providing a catalyst roaster belt (26) with an inorganic salt disposed thereon and supplying a heating medium to a first side of the catalyst roaster belt (26) such that heat from the heating medium flows through the catalyst roaster belt (26) to a second side of the catalyst roaster belt (26) to vaporize the inorganic salt.
